To a/ZZ whom t Wtcty concern:

Be itknown that I, JOHN C. BERTscH, a citizen of the United States, anda resident of Atlanta, in the county of Fulton and State of Georgia,have invented a new and Improved the water of condensation of steamcontains a certain quantity of air, and if this water be used for makingice the cakes of ice will have air-bubbles therein. To produceabsolutely clear ice, it isnecessary to eradicate the air-bubbles fromthe water by what is known as reboiling7 the water. In order to providean economical system for this purpose, the water of condensation shouldbe led to the reboiling apparatus at the highest possible temperature;and it is the object of my invention to keep the temperature of thiswater high, so that it may be economically reboiled. This end I attainby leading the condensed water from the condenser to the reboilingapparatus through means which pass into close proximity to the steam onits way to the condenser, thus heating the condensed water, so that whenit enters the reboiler it will be at a high temperature, facilitatingboiling it.

This specification is a speciiic description of two forms of theinvention, while the claims are definitions of the actual scope thereof.

Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure lis a diagram of one form of the invention. Fig. 2 is a sectionalview of a heater which I prefer to employ, and Fig. 3 isa diagram of amodified form of the invention.

Referring to Fig. I, ct indicates a pipe leading steam from the sourceof generation. In the practical application of the invention to anice-making plant this pipe will lead the exhaust-steam from the engines,pump, and other steam-consuming apparatus of the ice plant. The pipe ctpasses into a heating-drum b, and from this drum the steam passes by apipe c to a condenser d of any desired form. This condenser is of suchcharacter and capacity that as soon as all of the steam is condensed thecondensate is discharged from the condenser. From the condenser d a pipee leads back to a coilf in the drum Zi, and from this coil passes a pipeg to the reboiling apparatus h, which also may be of any constructiondesired. t' indicates a pipe passing from the bottom of the drum b tothe reboiling apparatus h to carry off fromlthe former the water ofcondensation therein. N ow it is clear that the steam passing into thecondenser d will be condensed and that the water of condensation runningtherefrom will pass through the coil f. This coil will be heated by thesteam in the drum b, and the water passing through the pipe g to thereboiling apparatus t will be at a temperature nearly approaching theboiling-point. that is condensed in the drum b will be led through thepipe t' to the reboiling apparatus` h. By this means I heat the water ofconu densation to a point nearly approaching the boiling-point withoutinvolving in anyway the expenditure of heat energy additional to thatoriginally required to generate the steam passing through the pipes a,and c.

In order to condense the steam fully and with that rapidity essential topractical-success, the temperature of the condenser must be much belowthat of the boiling-point of water, and hence the condensate will inpractice be at a temperature much below this boiling-point. Then bypassing this relatively cold water of condensation through theheating-coil f the temperature is again raised and reboilingfacilitated.

The construction shown in Fig. 2 involves Any steam l a tubular arm b',passing from the drum b y reboiling apparatus; but in Fig. 3 it iiows`IOO from the condenser to a tank Z by way of a pipe e', and from thistank the water is forced through the pipe e to the coilfin the drum band thence by the tube g to the reboiling 5 apparatus h.

YHaving thus described my invention, I claim as new and desire to secureby Letters Patentl. An apparatus for distilling Water, com- Io prising acondenser, a reboiling device, and means for leading thewater ofcondensation from the condenser to the reboiling device, said meanspassing into proximity to the steam as the steam passes to thecondenser,

I5 for the purpose specified.

2. An apparatus for distilling water, cornprising a condenser, a meansfor leading the steam therefrom, said means including a drum, areboiling device, and a means for 2o conducting the water ofcondensation from the condenser `to the reboiling device, said meansincluding a coil located in the drum, for the purpose specified.

3. An apparatus for distilling Water, comprising a condenser, means forleading` the z5 steam thereto, said means including a drum with a hollowarm or extension, a reboiling apparatus, and a means for leading thewater of condensation from the condenser to the reboiling apparatus,said means includ- 3o ing a coil located within the drum, and a pipepassing from the coil through the hollow arm or extension of the drum.

In testimony whereof I have signed my name to this specification in thepresence of 35 two subscribing witnesses. l
